3.2.10 Using the Reference Pulse Inhibit Function (INHIBIT)
For position control only.
1) Outline
This function inhibits a position control from counting input reference pulses.
While this function is being used, the motor remains in servo locked (clamped) status.
The P-CON
signal is used to enable or prohibit this function.
When this function is used, therefore, the P-CON
signal cannot be used to switch be-
tween proportion (P) control and proportional/integral (PI) control for speed loop. (PI con-
trol is always used.)
